'THAL, citizen of. the United States, residing at Mentor, in the countyof Lake and State of Ohio, have invented certain new and use fulImprovements in Knitted Fabric, of which the following is aspecification.

This invention relates to lmitted fabrics, and has for its object toprovide an improved ribbed fabric of fineappearance and ing 'inadeeither porous or close knit; The

fabric will have. the desirable elasticity of regular ribbed goods, andbeing made with a double web can have different colors on face and backas desired.

The fabric comprises two interlocked webs having front and back loopswhich are interwoven with other yarns to form ribs. The fabric is madeby employing both sets of needles, dial and cylinder respectively, theribs being sufficiently heavy to give body to the goods and the yarnsoftheribs being connected by loops which give elastic qualities and thejoining of the threads or yarns is not on the face of the fabric, beinginterwoven with front and back loops formed alternately in therespectiveyarns. Four courses are employed, one of which forms frontloops, another back loops, and the remaining two both front and backloops, the two latter forining ribs on'both faces, jhe wales on one facebeing equal to those on the other, with openings between to give aporous effect.

in the accompanying drawings-li igure 1 is a front face view of thefabric on an enlarged scale. Fig. 2 is a rear face view. Fig. 3 is aplan showing theloops of the various threads, detache Referringspecificallyto the drawings the respective threads or yarns of thefabric are indicated at 1, 2, 3 and 4, 1, being the courses forming theback web, .3 the courses forming the front web, and 2 and 4 the courseswhich interlock with the others, and the loops of which alternate withthe loops of the courses 1 and 2. Thus each back yarn 1 forms a seriesof single loops 1*. These 100 s are comparatively long and connect theribs on across the spaces intervenin s ecification of e ters t nt.Patented June 18, 1912.

being disposed at the front ofthe fabric, the

connecting pa'rts 2 extending through the fabric, the long loops 2 and 1being located .111 alternation. The front yarn 3 as a series [of shortsingle-loops 3 which drew under the necks of the loops 2 and floatbetween said loops,'at the front of the abric. It will thus be seen thatthe webs composed of the courses 1 and 3 are interwoven orinterlocked'by the long and short loops respectively of the course 2.The course 4 which is also an interlocking course has long loops 4* atthe back which draw over the short loops 2" at the back of the fabricand also has short loops 4 which draw under the loops 3 at the front,extending intermediately through the fabric in the'form of loops4 whichinterlock-through the loops 1" and 2 of the nextco'urse, and said yarns1 and 2, last mentioned, are in turn interwoven with each other and withthe successive yarns 3 and 4 111 a similar manner. a Y

. The courses 2 and-4, wherethey extend across the fabric in interwovenrelation with the courses 1' and 3, form a heavier body at regularintervals, producing the ribs in the fabric, partly in connection withthe adjato draw in, or away from the surface at both sides, so that thejoints Where the yarns cross are not exposed to wear. In consequence ofthis the fabric has great durability and afiner finish.

The wales containing the'loops 1 are lo- .cated at the side of thefabric opposite to threadsmay be varied to make the ribs more lessdense.

The above describes the produced fabric. With respectto the order andmanner of knitting, course 4 is knit on the cylinder and dial needles ofa rib knitting machine in one-and-one rib, the stitches beingalternately long and short; course 3 is then knit as a plain fabric uponeach of the cylinder needles only; course 2 is then knlt upon bothcylinders and dial needles as one-andone rib fabric; and course 1 isthen knit as a plain fabric uponeach of the dial needles. The result isa succession of one-course welts knit respectively upon the back or dialsides of the fabric and upon the front or cylinder side of the fabric,said welts bein united by a single course of one-and-one r1 fabrlc.

The invention is not limited to the. exact embodiment shown, as thenumber of courses or stitches, particularly in the welts and the ribs,may be varied, within the scope of the following claims.

I claim:

1. A knitted fabric comprising a succession of one walled welts one setof which is exclusively on one side of the fabric and another set ofwhich is exclusively on the opposite side of the fabric, and rib courses'30 connecting said welts.

2. A knitted fabric comprising a succession of one-walled wel'ts some ofwhich are knit exclusively on one side of the fabric and others of whichare knit exclusively on the other side of the fabric, and courses ofone-and-one rib uniting said welts.

- 3. A knitted fabric comprising a succession of one-course. welts knitrespectively on opposite sides of the fabric, and single 40 courses ofone-and-one rib uniting said welts.

4. A knitted fabric comprising a succession of welt courses knitrespectively on opposite sides of the fabric, .and courses ofone-and-one rib uniting said welts, said rib courses having alternatelong and short loops.

5. A knitted fabric comprising a succession of welt courses knitrespectively on opsite sides of the fabric, and rib courses connectingsaid welts, the wales containing the loops of the welt courses on oneside of the fabric being in alternation with the wales containing theloops of'the welt courses on the other side.

6. A knitted fabric comprising a succes-' sion of one walled weltcourses one set of which has comparatively long loops and is knitexclusively on one side of the fabric and another set of which hasshorter loops and is knit exclusively on the, other side ofv the fabric,and one-and-one rib courses uniting said welts, the rib courses havinglong and short loops corresponding to the long and short loops of therespective welt courses. v

7. A knitted fabric comprising a succession of welt courses knitrespectively on opposite sides of the fabric, and rib courses connectingsaid welts, the wales containing the loops of the welt courses on oneside of\ the fabric being in alternation with the wales containing theloops of the welt courses on the other side, and the rib courses havinglong loops in the wales on one side of the fabric and short loops in thewales on the other side.

8. A ribbed knitted fabric having onewalled welt courses on oppositesides respectively, the courses on each side being exclusively on suchsides.

' 9. A ribbed knitted fabric having a succession of one-walledwelt'courses in alternation on opposite sides respectively, the

courses on each side being exclusively on such side.

10. A ribbed lmitted fabric having a sucsession of welt courses inalternation on opposite sides respectively, the wales-containing theloops of the welt courses on one side being in alternation with thewales containing the loops on the Welt courses on the other side, of thefabric.

In testimony whereof, I do aflix my signature in presence of twowitnesses.
